Unlocking your BlackBerry allows you to use SIM cards from other providers.
To openline your BlackBerry means to unlock the SIM card. When your purchase your BlackBerry from a service provider, the phone is locked so that it cannot be used with other SIM cards or other providers. You can have your phone unlocked if you have the unlock code and your IMEI number, which is your phone's identification number. Obtaining the unlock code may not be easy, but some service providers are willing to provide it to you. Alternatively, you can pay a one-time fee and receive the unlock code, for which you can then use with as many SIM cards as you require.
